I've been reading a lot about cosmology lately. Mostly higher level abstractions about how things work without really wanting to get dragged or pulled down by some of the maths. My eyes kind of glaze over an equation when I see one on a wikipedia article.

But that got me to thinking; I was never particularly bad at math, even though I was always afraid I didn't understand it "all the way." I'm better with programming, which is similar, but not always as number oriented. Anyways, the last math I took was Pre-calculus Algebra, and that was about a year or so ago.

I'm not really interested in pursuing a physics degree or anything career-oriented/professional, but I

**like to self-study physics and math for personal enrichment.**

*would***Any suggestions about where to start?**My precalc is probably rather rusty; should I work on that? Perhaps pull that old book out and start chugging through the chapters and exercises again? Ultimately I'd like to learn calculus and trig, perhaps use that knowledge to help in programming basic orbital calculations, etc.
